Description

Technical Field

[0001] The present invention relates to the technical field of aerosols, and in particular to a device for generating active particle water mist aerosol and a preparation method thereof. Background Art

[0002] Existing ozone disinfection and sterilization machines can generate ozone for disinfection and sterilization, but the generated ozone is released directly into the air. Ozone flows everywhere in open spaces, so it cannot stay on the surface of the disinfected items for a long time to achieve the desired sterilization effect. In addition, ozone flows everywhere in open spaces and will directly react with suspended matter, bacteria, and odors in the air, decomposing and destroying them, making it difficult to achieve a good sterilization effect in the specific area to be sterilized.

[0003] In view of the above-mentioned deficiencies, it is necessary to design a device for generating and preparing an active particle water mist aerosol. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the ozone generated by the ozone disinfection and sterilization machine in the prior art is directly released into the air and has poor sterilization effect, thereby providing a generating device and preparation method of active particle water mist aerosol.

[0019] 2. In the active particle water mist aerosol generating device provided by the present invention, the discharge needle of the discharge device is a capillary with a hollow surface, so that the setting angle of the discharge needle is not limited to the discharge end pointing vertically downward, thereby improving the adaptability of the discharge needle setting angle. In addition, the needle cover is made of a porous material and can continuously absorb moisture from the air and store it in the needle cover, ensuring the stability of the water source required by the discharge device and improving the convenience of obtaining the water source.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0046] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] Example 1

[0048] like Figures 1 to 8 As shown, this embodiment provides a device for generating active particle water mist aerosol, including a water tank A, a discharge device B, an atomizer C and an air pump D.

[0049] Water tank A is suitable for holding water and forming an air chamber 44 above the water surface. An air inlet 41 and an air outlet (not labeled) are provided on the wall of water tank A. Both the air inlet 41 and the air outlet are connected to the air chamber 44, and the total cross-sectional area of ​​the air outlet is larger than the total cross-sectional area of ​​the air inlet 41. The air inlet 41 provides a passage for outside air to enter the air chamber 44, and the air outlet provides a passage for the active particle water mist aerosol within the air chamber 44 to be released outside the water tank A. In this embodiment, water tank A is provided with an upper cover 4, on which both the air inlet 41 and the air outlet are provided. The air outlet upper cover is provided with a lid 43. The lid 43 is normally closed. Of course, it can also be set to a normally open state, and when preparing the active particle water mist aerosol, the lid 43 is closed to seal the air outlet. The air inlet 41 is a Venturi-structured air inlet 41 and is normally open. An air replenishment device (not shown) replenishes air into the air chamber 44 through the air inlet 41 along the air inlet duct. When the cover 43 on the air outlet is in a closed state, the air chamber 44 can only be connected to the outside through the air inlet 41, and air can only enter the air chamber 44 from the air inlet 41, and cannot flow outward from the air chamber 44 through the air inlet 41, thereby avoiding leakage of active particle water mist aerosol.

[0050] The discharge device B is mounted on the wall of the water tank A. The discharge device B comprises a metal sheet 1, a discharge needle 2, and a needle sleeve 3. The discharge needle 2 extends into the air chamber 44, and the needle sleeve 3 is sleeved on the outside of the discharge needle 2. The discharge end 24 of the discharge needle 2 protrudes from the needle sleeve 3. When the discharge device B is energized, the discharge needle 2 can ionize the air to produce ozone, and can also discharge water that reaches the discharge end 24 of the discharge needle 2 to produce negative oxygen ions. Active particles such as ozone and negative oxygen ions are released into the air chamber 44. In addition, the amount of ozone and negative oxygen ions produced can be adjusted by adjusting the length of the discharge end 24 of the discharge needle 2 exposed to the needle sleeve 3. In this way, active particles mainly composed of ozone or mainly composed of negative oxygen ions can be produced.

[0051] The metal sheet 1 is in the shape of an elongated strip and is suitable for connecting to a high-voltage power supply. Different numbers of discharge needles 2 can be connected to the metal sheet 1 as required.

[0052] The discharge needle 2 is made of a conductive material. Of course, it can also be made of a non-conductive material but with a conductive coating applied to the outer surface or the inner and outer surfaces. In this embodiment, the discharge needle 2 is hollow and is a capillary tube. The surface has multiple through holes 21, which makes the surface of the discharge needle 2 appear hollow. One end of the discharge needle 2 is connected to the metal sheet 1, and the end away from the metal sheet 1 is the discharge end 24. In addition, the portion of the discharge needle 2 adjacent to the metal sheet 1 and exposed from the needle sleeve 3 is called the root 23 of the discharge needle 2. The root 23 of the discharge needle 2 is provided with an air supply hole 22, which is suitable for replenishing air into the discharge needle 2 through the air supply hole 22, so that air circulation is formed in the hollow discharge needle 2. The shape of the air supply hole 22 can be different from the shape of the through hole 21, or it can be the same as the shape of the aforementioned through hole 21.

[0053] The needle guard 3 is made of a porous material. Its porous properties continuously absorb moisture from the air within the air chamber 44 and store it within the guard 3. A hydrophilic material may be added to the porous material of the guard 3 to increase its hydrophilicity and enhance its ability to absorb moisture from the air. Alternatively, a hydrophilic coating may be applied directly to the surface of the guard 3. The guard 3 is positioned over the discharge needle 2, with the inner wall of the guard 3 in contact with the outer wall of the discharge needle 2. Moisture absorbed by the guard 3 enters the inner wall of the discharge needle 2 through the through-hole 21 and flows toward the discharge end 24 under the siphon effect of the capillary tube.

[0054] In this embodiment, the working process of the discharge device B is as follows:

[0055] The needle sheath 3 continuously absorbs the moisture in the air chamber 44 and stores it in the needle sheath 3;

[0056] The water in the needle sleeve 3 enters the inner wall of the discharge needle 2 from the through hole 21 on the discharge needle 2 to form a water film, and flows toward the discharge end 24 under the siphon effect of the capillary;

[0057] High voltage electricity is applied to discharge needle 2 through metal sheet 1, creating a potential difference between the discharge end 24 of discharge needle 2 and the air. Air particles at discharge end 24 are affected by the high voltage electric field, forcing them to be either plundered or endowed with the same charge. Based on the principle of like charges repelling like charges, like-charged air particles quickly leave discharge end 24 of discharge needle 2 and form an ion wind. The term "plundered" refers to the application of positive high voltage, which causes a large number of free electrons in air particles to be plundered and enter the power supply, forming a large number of positively charged air ions. The term "endowed" refers to the application of negative high voltage, which causes air particles to combine with the free electrons provided by the power supply, forming a large number of negatively charged air ions. In this embodiment, since discharge needle 2 is a capillary tube, the internal space of the capillary tube allows air particles to move for a longer period of time in an environment with a higher spatial electric field density during operation, thereby better energizing the air particles passing through the capillary tube and more easily generating charged air particles. The so-called energization refers to the uncharged air particles entering the capillary. During the movement of the uncharged air particles inside the capillary, due to the action of the electric field, the overall kinetic energy of the air particles increases, the movement speed increases, especially the movement speed of the electrons outside the nucleus increases. The air particles in this high-energy state are more likely to lose free electrons. At the same time, free electrons can also be captured to reduce the runaway state of the air particles.

[0058] The flow of ionized wind causes air to flow from the base 23 of the discharge needle 2 toward the discharge end 24 of the discharge needle 2. The water film on the inner wall of the discharge needle 2 moves toward the discharge end 24. Once at the discharge end 24, the water film is shredded by the air pressure generated by the ionized wind, producing extremely small water particles. These extremely small water particles are then activated by high voltage electricity, with some ionized or injected with additional free electrons, generating extremely small active particles such as negative oxygen ions and hydroxyl radicals. Of course, during this process, air needs to be replenished into the discharge needle 2 through the air replenishment hole 22 on the capillary tube, located outside the needle sleeve 3, to form an air circulation system to continuously replenish the air.

[0059] The discharge device B in this embodiment absorbs moisture from the air through a needle sleeve 3 made of a porous material. This moisture is stored within the needle sleeve 3, ensuring the water source required for high-voltage ionized water and improving water accessibility, thereby ensuring the production of active particles such as hydroxyl radicals. Furthermore, the negative oxygen ions produced are greater than those produced by a solid discharge needle 2 coated with a porous, water-absorbing material. This is because, compared to a solid needle, a layer of water film is added within the capillary, which produces a number of water ions that a solid needle cannot provide. Furthermore, since the discharge needle 2 is a capillary, water flows within the capillary via siphoning. This allows the placement of the capillary discharge needle 2 to be no more limited to a vertically downward placement of the discharge end. This improves the adaptability of the capillary discharge needle 2 to a specific angle, allowing the capillary discharge needle 2 to be positioned at an angle of no less than 45 degrees relative to the horizontal.

[0060] Air pump D is located within water tank A. Its air inlet 41 is located within air chamber 44, and its air outlet is submerged in the water within tank A. Air pump D is adapted to pump the air containing active particles within air chamber 44 into the water, forming active particle water. When ozone is the primary active particle, the resulting active particle water is referred to as ozone water. When negative oxygen ions are the primary active particle, the resulting active particle water is referred to as active water. Pumping active particles into water reduces their decomposition rate compared to directly releasing them into the air, thereby extending their lifespan.

[0061] Atomizer C is immersed in the water in water tank A. Atomizer C is suitable for atomizing the active particle water in water tank A into active particle water mist to mix with the air in the air chamber to form an active particle water mist aerosol. The active particle water mist aerosol is suitable for being released from the open air outlet along the air outlet duct to the outside of water tank A. In this embodiment, atomizer C is an ultrasonic atomizer, and the mist outlet of atomizer C is located 2-3 cm below the water surface to achieve a better atomization effect. Preferably, a buoy (not shown) is added to the other end of the air inlet 41 of atomizer C. On the one hand, it can control the atomizer C to always be at the liquid level depth with the best atomization effect. On the other hand, it can be used as a buoy to mark the upper and lower water levels, limit the working water level range of atomizer C, and ensure safety.

[0062] As a supplementary explanation, in this embodiment, the air replenishing device replenishes air into the air chamber 44 along the air inlet duct through the air inlet 41, forcing the active particle water mist aerosol in the air chamber 44 to be released outward along the air outlet through the open air outlet. In this way, there is no need to set up a gas power device in the water tank A.

[0063] Of course, the discharge needle 2 may not be provided with the needle cover 3. The discharge needle 2 is a bare needle. After the discharge device B is connected to high voltage electricity, the discharge needle 2 ionizes the air to produce ozone. In this case, the active particles are mainly ozone.

[0064] In this embodiment, the discharge needle 2 of the discharge device B can ionize the air to produce ozone or discharge the water at the discharge end 24 of the discharge needle 2 to produce negative oxygen ions. The active particles such as ozone and negative oxygen ions are pumped into the water in the water tank A by the air pump D to form active particle water. The atomizer C can atomize the active particle water in the water tank A to form active particle water mist and mix it with the air to form an active particle water mist aerosol. The active particle water mist aerosol is released outward along the air outlet through the open air outlet and reaches the target area. The active particle water mist aerosol can exist in the target area for a long time, thereby extending the disinfection and sterilization time and improving the disinfection and sterilization effect.

[0065] Example 2

[0066] This embodiment provides a method for preparing an active particle water mist aerosol, which is prepared using the aforementioned active particle water mist aerosol generating device and includes the following steps:

[0067] S1. Add water to the water tank A until the water level covers the mist outlet of the atomizer C and the air outlet of the air pump D and is lower than the needle sleeve 3 of the discharge device B.

[0068] S2, the gas outlet is closed, the discharge device B is energized, the discharge needle 2 discharges to generate active particles and releases them into the gas chamber 44;

[0069] S3. After the discharge device B is powered on for 1 minute, the air pump D is turned on to pump the air containing the active particles in the air chamber 44 into the water in the water tank A to form active particle water. Of course, the discharge device B can be powered on for more than 1 minute before the air pump D is turned on.

[0070] S4. After the discharge device B is powered on for 10 minutes, the atomizer C is turned on. The atomizer C atomizes the active particle water into active particle water mist, which mixes with the air in the air chamber to form an active particle water mist aerosol. The concentration of the active particles can be adjusted by controlling the power-on time of the discharge device B.

[0071] S5. Turn off the discharge device B, and keep the air pump D and the atomizer C turned on until the concentration of the active particle water mist aerosol reaches the preset concentration value;

[0072] S6. Open the air outlet, and the active particle water mist aerosol is released outward from the air outlet along the air duct.

[0073] In this embodiment, air pump D pumps the active particles released by discharge device B after power is applied into water, forming active particle water. The active particles are then atomized by atomizer C to form active particle water mist. The active particle water mist mixes with air to form an active particle water mist aerosol. The active particle water mist aerosol is released out of the water tank through the open air outlet and along the air outlet duct to reach the target area. The active particle water mist aerosol can remain in the target area for a longer period of time, thereby extending the disinfection and sterilization time and improving the disinfection and sterilization effect. In addition, when the active particles are pumped into water, the decomposition rate of the active particles is reduced compared to when the active particles float in the air, thereby extending the lifespan of the active particles.

[0074] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
